TL;DR: An intelligent energy management system for switch mode power supply (SMPS) is developed to distribute the energy to four different telecom operator effectively and measure energy consumption by each of the telecom operator using that SMPS.
Abstract: The number of mobile users is increasing every day. Increased user cause extra stress on base trans-receiver station (BST) covering particular area, which result into extra power requirement of that antenna. Because of less energy, developing an intelligent energy management system for switch mode power supply (SMPS) is more important to use power efficiently. Objective is to distribute the energy to four different telecom operator effectively. Measure energy consumption by each of the telecom operator using that SMPS. Another objective is to monitor energy consumptions at remote location for each operator using Internet of the things (lOT).

TL;DR: The reasons underlying the performance improvement are described and the experimental results confirming that SJ MOSFETs with very fast diode is the suitable technology to be used for telecom zero voltage switching SMPS are presented.
Abstract: The increasing demand of electronic systems in car electrification as well as in IoT (internet of thing) applications requires power supply with large power output, high efficiency, and small size factor. In this framework, the main topologies used for telecom switch-mode-power-supply (SMPS) have been investigated in this paper. Performance and reliability of the SMPS are mainly related to the MOSFET characteristics, and a primary aspect of such high-level applications is to ensure the service continuity. The new products of super junction (SJ) MOSFETs with very fast diode are the best candidate to match the above expectations. This work describes the reasons underlying the performance improvement and presents the experimental results confirming that SJ MOSFETs with very fast diode is the suitable technology to be used for telecom zero voltage switching SMPS.

TL;DR: In this paper, a new teaching model of engineering circuit courses is proposed to use experimental learning to drive theoretical study, which make students better fit the company's work, transform the traditional test score based final examination to the process evaluation, which is consistent with the proposed teaching model.
Abstract: This paper presents "Truth from Practice, Learning beyond Teaching", a new teaching model of engineering circuit courses. It is proposed to use experimental learning to drive theoretical study, which make students better fit the company’s work, transform the traditional test score based final examination to the process evaluation, which is consistent with the proposed teaching model. This paper presents a curriculum framework that establishes the combination of higher education and social production used in the supply power circuit course. The syllabus of the reform includes lectures, laboratories, projects and the procedure for evaluation focuses on process. In the contest of higher engineering education, autonomous learning and innovation are seen at the key factors of knowledge-based society, adapt the proposed education approach to cope with ongoing and future problems. The use of this teaching model to significantly motivates students to broaden their knowledge widely and to improve the quality of the course, enable scientific research techniques to solve practical problems more effectively, and avoid the blindness of talent cultivation.

TL;DR: In this article, real and reactive power management strategies of EI-DG units in the context of a multiple DG microgrid system were investigated. And the results were used to discuss applications under various microgrid operating conditions.
Abstract: This paper addresses real and reactive power management strategies of electronically interfaced distributed generation (DG) units in the context of a multiple-DG microgrid system. The emphasis is primarily on electronically interfaced DG (EI-DG) units. DG controls and power management strategies are based on locally measured signals without communications. Based on the reactive power controls adopted, three power management strategies are identified and investigated. These strategies are based on 1) voltage-droop characteristic, 2) voltage regulation, and 3) load reactive power compensation. The real power of each DG unit is controlled based on a frequency-droop characteristic and a complimentary frequency restoration strategy. A systematic approach to develop a small-signal dynamic model of a multiple-DG microgrid, including real and reactive power management strategies, is also presented. The microgrid eigen structure, based on the developed model, is used to 1) investigate the microgrid dynamic behavior, 2) select control parameters of DG units, and 3) incorporate power management strategies in the DG controllers. The model is also used to investigate sensitivity of the design to changes of parameters and operating point and to optimize performance of the microgrid system. The results are used to discuss applications of the proposed power management strategies under various microgrid operating conditions

TL;DR: A noncooperative Stackelberg game between the RUs and the SFC is proposed in order to explore how both entities can benefit, in terms of achieved utility and minimizing total cost respectively, from their energy trading with each other and the grid.
Abstract: In this paper, the benefits of distributed energy resources are considered in an energy management scheme for a smart community consisting of a large number of residential units (RUs) and a shared facility controller (SFC). A noncooperative Stackelberg game between the RUs and the SFC is proposed in order to explore how both entities can benefit, in terms of achieved utility and minimizing total cost respectively, from their energy trading with each other and the grid. From the properties of the game, it is shown that the maximum benefit to the SFC, in terms of reduction in total cost, is obtained at the unique and strategy-proof Stackelberg equilibrium (SE). It is further shown that the SE is guaranteed to be reached by the SFC and RUs by executing the proposed algorithm in a distributed fashion, where participating RUs comply with their best strategies in response to the action chosen by the SFC. In addition, a charging–discharging scheme is introduced for the SFC's storage device that can further lower the SFC's total cost if the proposed game is implemented. Numerical experiments confirm the effectiveness of the proposed scheme.

TL;DR: This study proposes a DR energy management scheme for industrial facilities based on the state task network (STN) and mixed integer linear programming (MILP) and takes advantage of distributed energy resources (DERs) to implement DR.
Abstract: Demand response (DR) smart grid technology provides an opportunity for electricity consumers to actively participate in the management of power systems. Industry is one of the major consumers of electric power. In this study, we propose a DR energy management scheme for industrial facilities based on the state task network (STN) and mixed integer linear programming (MILP). The scheme divides the processing tasks in industrial facilities into nonschedulable tasks (NSTs) and schedulable tasks (STs), and takes advantage of distributed energy resources (DERs) to implement DR. Based on day-ahead hourly electricity prices, the scheme determines the scheduling of STs and DERs in order to shift the demand from peak periods (with high electricity prices) to off-peak periods (with low electricity prices), which not only improves the reliability of the electric power system, but also reduces energy costs for industrial facilities.
